Exact Answer

==================================================
Problem: What is 4/27 plus 2/10?
Formula / Expression: 4/27 + 2/10
Final Answer: 47/135
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 27 and 10 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 27 × 10 = 270.
Working: LCD(27, 10) = 270

Step 2: Convert to Equivalent Fractions with Common Denominator 270
Multiply the numerator and denominator of 4/27 by 10, and multiply the numerator and denominator of 2/10 by 27 so both fractions share the common base 270.
Working: 4 × 10/27 × 10 = 40/270 and 2 × 27/10 × 27 = 54/270

Step 3: Add the Numerators
Now add the numerators (40 + 54 = 94) and keep the common denominator 270 unchanged.
Working: 40 + 54/270 = 94/270

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 94 and 270, which is 2. Divide both the numerator and denominator by 2.
Working: 94 ÷ 2/270 ÷ 2 = 47/135

Step 5: Decimal & Percentage Representation
Dividing the numerator 47 by denominator 135 produces a repeating decimal (approximately 0.348148, or 34.8148%).
Working: 47 ÷ 135 = 0.348148 (34.8148%)

Key Values:
- Simplified Fraction: 47/135
- Mixed Number Form: 47/135
- Decimal Value: 0.348148

Step-by-Step Solution: 4/27 + 2/10

Step 1

Find the Least Common Denominator (LCD)

The denominators 27 and 10 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 27 × 10 = 270.

LCD(27, 10) = 270

Step 2

Convert to Equivalent Fractions with Common Denominator 270

Multiply the numerator and denominator of 4/27 by 10, and multiply the numerator and denominator of 2/10 by 27 so both fractions share the common base 270.

4 × 10/27 × 10 = 40/270 and 2 × 27/10 × 27 = 54/270

Step 3

Add the Numerators

Now add the numerators (40 + 54 = 94) and keep the common denominator 270 unchanged.

40 + 54/270 = 94/270

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 94 and 270, which is 2. Divide both the numerator and denominator by 2.

94 ÷ 2/270 ÷ 2 = 47/135

Step 5

Decimal & Percentage Representation

Dividing the numerator 47 by denominator 135 produces a repeating decimal (approximately 0.348148, or 34.8148%).

47 ÷ 135 = 0.348148 (34.8148%)
